Electricity and Magnetism Mr. Chinua Mosley Electricity Electromagnetism Electric Stuff Series Circuit Parallel Circuit Electric Circuits An electromagnet is a magnet that is made by sending an electric current through a wire wrapped around a magnetic metal. A conductor is a material that allows electricity to flow freely through it. An electric circuit is a pathway for electric current. A series circuit is a circuit where all of the loads are placed back to back. A parallel circuit is a circuit that has multiple paths to complete the circuit. Electric current is the flow of electric charges The current creates a magnetic field around the magnetic metal that can be turned off by turning of the current This is an example of an electromagnet wire magnetic metal An electric current is coming from the battery What can a huge electromagnet do? An insulator is a material that doesn't allow electricity to flow through it. Metals and salt water are examples of conductors. Wood, rubber, and plastic are examples of insulators A circuit has 4 basic parts. A circuit needs an energy source like a battery. The energy source pushes the charge through the circuit. A circuit needs a load like a light bulb. The load is the device that uses the electrical energy and converts it to another type of energy like light or heat energy. Circuits need a conductor like metal wire. Conductors are materials that let electricity flow freely though them to all parts of the circuit. Most of the time a circuit has a switch. A switch makes the circuit an open or closed circuit by connecting or disconnecting the flow of electrons. The main issue with a series circuit is that when one load breaks it makes the circuit an open circuit. Another issue is that every load in the series gets more energy than the load behind it. All of the loads on a parallel circuit get the same amount of electricity. If one load breaks, the circuit is still closed. A closed circuit is a complete loop that allows the electricity to flow through the entire circuit. An open circuit is an incomplete loop that does not allow electricity to flow through the entire circuit. Closed Circuit Open Circuit Electrical energy or electricity is generated by the movement of charged particles
